virtualbox 来宾添加：错误：内核配置无效

Question

我做了什么：

1. 安装最小的 debian/testing（没有 GUI，没有标准实用程序）
2. 安装 build-essential, dkms, linux-headers-$(uname -r)
3. 单击设备 -> 插入访客添加 CD
4. 跑了 m-a prepare
5. 安装在/dev/sr0某处，cd那里和./VBoxLinuxAdditions.run

我得到了什么：

...
Building the modules for kernel 5.4.0-4-amd64.
Look at /var/log/vboxadd-setup.log to find out what went wrong.
modprobe vboxsf failed
...

日志中的内容：

...
test -e include/generated/autoconf.h -a -e include/config

/auto.conf || (                \
    echo >&2;                                                       \
    echo >&2 "  ERROR: Kernel configuration is invalid.";           \
    echo >&2 "         include/generated/autoconf.h or include/config/auto.conf are missing.";\
    echo >&2 "         Run 'make oldconfig && make prepare' on kernel src to fix it.";      \
    echo >&2 ;                                                      \
    /bin/false)
    ...

我调查的内容：

    $modprobe vboxsf
    modprobe: FATAL: Module vboxsf not found in directory /lib/modules/5.4.0-4-amd
    $lsmod | grep vboxsf
    <no output>
    $find /usr/src/linux-headers-5.4.0-4-amd64/ -name autoconf.h
    /usr/src/linux-headers-5.4.0-4-amd64/include/generated/autoconf.h

主机操作系统是 Ubuntu 18。

编辑：安装 openbox 以获取 X 服务器后，日志如下所示：

Answer 1

问题似乎与 virtualbox 安装附带的来宾添加 iso 有关。最好的选择是从存储库下载来宾添加。

1. 运行sudo apt install virtualbox-guest-additions-iso以获取最新的存储库
2. 里面会下载来宾iso /usr/share/virtualbox/VBoxGuestAdditions.iso
3. 创建挂载点并挂载iso： sudo mkdir -p /mnt/cdrom && sudo mount /usr/share/virtualbox/VBoxGuestAdditions.iso /mnt/cdrom
4. 导航到iso并安装： cd /mnt/cdrom && sudo sh ./VBoxLinuxAdditions.run --nox11

Answer 2

fallthrough虚拟机来宾添加驱动程序中与gcc 属性相关的宏与 Linux 内核头文件之间似乎存在冲突。

具体来说，虚拟盒驱动程序定义了几个这样的宏：

root@vdebtest:/usr/src/vboxguest-5.1.38$ grep fallthrough -R
vboxvideo/include/iprt/cdefs.h:# define RT_FALL_THROUGH()      __attribute__((fallthrough))
vboxguest/include/iprt/cdefs.h:# define RT_FALL_THROUGH()      __attribute__((fallthrough))
vboxsf/include/iprt/cdefs.h:# define RT_FALL_THROUGH()      __attribute__((fallthrough))

但在 Linux 内核的include/linux/compiler_attributes.h中，有这样的内容：

/*
 * Add the pseudo keyword 'fallthrough' so case statement blocks
 * must end with any of these keywords:
 *   break;
 *   fallthrough;
 *   goto <label>;
 *   return [expression];
 *
 *  gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes
 */
#if __has_attribute(__fallthrough__)
# define fallthrough                    __attribute__((__fallthrough__))
#else
# define fallthrough                    do {} while (0)  /* fallthrough */
#endif

现在，如果我正确理解你的构建日志，我认为这些RT_FALL_THROUGHs 实际上最终会变成__attribute__((__attribute__((__fallthrough__))))，弄乱代码。

您可以尝试进入您的/usr/src/vboxguest-x.y.z目录并将所有__attribute__((fallthrough))（它们只是我的设置中的其中 3 个）替换为 吗__attribute__((__fallthrough__))？（falthrough我想普通也应该有效）...

然后通过 重建所有这些./build_in_tmp。

更新：我看到不久前有人对此主题有一些抱怨。而且似乎已经通过这张票解决了。
